- The present invention relates to dual flush valve and it consists inthe combinations, constructions and arrangements of parts hereindescribed and claimed;

It is an object of the present invention to provide an attachment forthe conventional flush tank having means whereby a portion orsubstantially all of the water therein may selectively be dispensedtherefrom.

Another object of the invention is the provision of a novel arrangementof selectively operable valves in a flush tank.

A further object of the invention is the pro.- vision of a novelarrangement of levers for operating a plurality of valves in a fl ushtank.

Another object of the invention is the provision of a device of thecharacter set forth wherein all of the component parts are of standardor conventional character.

A still further object of the invention is the provision of novel meansand mechanism for latching in position a bearing sleeve forming a partof the invention.

Another object of the invention is the provision of an apparatus of thecharacter set forth which is simple in its construction and operationand eflicient and effective in use.

Another object of the invention is the provision of an apparatus of thecharacter set forth in which the parts thereof may be easily repairedand replaced.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawings, in which:

Figure 1 is a fragmentary elevational view, partly in section, of anembodiment of the invention,

Figure 2 is a fragmentary sectional View taken along line 2-2 of Figure1,

Figure 3 is a fragmentary sectional view taken along line 3-3 of Figure1,

Figure 4 is an enlarged fragmentary sectional view taken along line 4-4of Figure 1,

Figure 5 is an enlarged sectional view taken along line 5-5 of Figure 2,

Figure 6 is an enlarged fragmentary sectional view taken along line 6- 5of Figure 2, and

Figure 7 is a fragmentary sectional view taken along line 1---'! ofFigure 4.

Generally, there is provided an attachment for a flush tank which mayreadily be inserted therein and which consists of a drain pipeconnection formed integrally with a hollow base having a 1 Claim. (Cl.4-37) valve seat therein and an upwardly extending 55 tubular connectionhaving a valve seat in the upper end thereof. A drain pipe also extendsupwardly from the hollow base. Hollow rubber ball valves are seated ineach of the aforementioned valve seats and are each provided with anupwardly extending wire connection which interconnects with a lever;Through the front face of the tank extends a bearing sleeve in which arerevolubly mounted a pair of nested shafts each provided with anoperating handle without the tank and each connected with one of thelevers within the tank whereby operation of one of the handles willcause the dispensing of approximately half of the water in thetankthrough the drain pipe and whereby operation of the other handle willcause the drainingof substantially all of the water through theaforesaid drain pipe.

Referring more particularly to the drawings, there is shown therein aflush tank l having the conventional opening II in the bottom thereofand provided with a conventional cover l2. Through the opening I Iextends a drain pipe connection 13 which is integrally formed with anddependant from a hollow base member I4 whose upper face I is providedwith a valve seat IS in which is seated a rubber ball valve I! providedwith an upwardly extending stem it which extends through a guide memberI9 and which is pivotally connected at its upper end to a lever 20.

A conventional overflow pipe 2| extends upwardly from the base I 4 andhas clamped thereto, as indicated at 22, the guide member I9 and hasalso clamped thereto, as indicated at 23, a guide member 24.

The base M has upwardly extending therefrom a hollow cylindrical memberhaving a valve seat 26 in the upper end thereof in which is seated arubber ball valve 21 having an upwardly extending stem 28 extendinthrough the guide member 24 and pivotally connected at its upper end toa lever 29.

The lever 20 is provided with a yoke 30 at its inner end which yokesurrounds a hollow shaft 3i and is clamped thereto by means of a, screw32. The shaft 3! extends through a bearing sleeve 33 which is square inits outer cross sectional periphery and which extends through a squareopening 34 in the front wall 35 of the tank Ill. The outer end of theshaft 3| is provided with an operating handle 36 and the outer end ofthe sleeve 33 is provided with a collar 31 formed integrally therewithand adapted to limit inward movement of the sleeve into the front wall35.

Revolubly mounted within the shaft 3| is a 3 shaft 38 whose outer end isprovided with an operating handle 39 and whose inner end extends througha yoke Ml formed integrally with the lever 29 and which yoke is clampedto the shaft 38 by means of a screw 4|.

A stabilizing clamp member 42 is provided with a yoke 43 which isclamped upon the sleeve 33 by means of a screw 44 and which is providedwith a stabilizing screw 45 which extends therethrough and which bearsagainst the innersi'de-of the wall 35.

In operation, it will be apparent that when a. minimum of "water isneeded for flushing purposes from the tank l9, it is only necessary tolift the handle 39 which Will cause the shaft 38 to revolve and lift thelever 29 thereby lifting the stem 28 and, consequently, theball valve21:. This action will allow water to flow through the cylindrical member25 to the interior of the base l4 and thence through the drain pipe 13.By virtue of the height of the member 25 only approximately one-half ofthe water in the tank Ill will be dispensed therefrom. However, if it isdesired to substantially completely empty the tank Iii it is onlynecessary to depress the handle 35 which will cause the shaft 3! torevolve thereby lifting the lever 20 and hence the stem 59 to unseat thevalve [1 from its seat 16 thereby allow ing practically all of the Waterin the tank 19 to be dispensed through the drain pipe 13'.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed is:

An apparatus of the character described comprising, in combination, aflush tank, a hollow base member, a drain pipe dependent from the basemember and adapted to extend through the bottom of the tank, a valveseated in the top of the base member, a pipe connected with the top ofthe base member and extending upwardly approximately half of the depthof the tank, a valve seated in the top of the upwardly extending pipe,vertical stems affixed to each of the valves, a lever connected to theupper end of each of the stems, a bearing sleeve non-revolubly mountedin the front wall of the tank, a hollow shaft revolubly mounted in thesleeve and afilxed to one of the levers, a solid shaft revolubly mountedin the hollow shaft and affixed to the other lever, an operating handleaffixed to the outer end of each of the shafts and means for rigidlymaintaining the bearing sleeve in position, said means comprising a yokeclamped about the sleeve'adj'acent the inner face of the front wall ofthe tank, a collar for the: sleeve upon the; outer side of the wall anda screw threaded in. the yoke and bearing against the inner face of saidwall.
